I will be snappy about this, as I've been trying to find a solution for a good few hours but no no avail.

I decided to try my hand at learning my way through mobile textures by ripping the textures from Dead Space iOS (I legally own the game before it was taken down from the store). I managed to get my hands on the .vpk and open it via changing its extension to .zip, but after navigating to texture assets, I was met with a huge roadblock.

From my understanding, m3g files stand for Mobile 3D graphics, and has been commonly used for mobile 3D rendering for quite a long time.

The problem is, though, that I have absolutely no idea how to open or access them, and I have tried multiple programs that came up with nothing.
